Oral symptoms potentially associated with mild-to-moderate COVID-19 in tobacco users.

Coronavirus disease (COVID-19) is a worldwide infection characterized by various symptoms. Few studies have examined its oral manifestations. However, there is insufficient information on the oral manifestations of patients with COVID-19 who use tobacco products. Therefore, this cross-sectional study investigated oral symptoms of tobacco-using patients with mild-to-moderate COVID-19. This study used a convenience sample of non-hospitalized patients (aged ≥18 years) with mild-to-moderate COVID-19 diagnosed by polymerized chain reaction (PCR). This study excluded pregnant or lactating women or patients with serious COVID-19 complications, including those who required hospitalization or were on specific medications (antiviral, corticosteroid, antimicrobial, or immunosuppressive). Oral examinations were performed, including labial, buccal, and gingival mucosa, tongue, floor of the mouth, and palate, for any newly developed lesions associated with the onset of COVID-19. The salivary flow was determined using the passive drool collection technique. Lip dryness, gingivitis, tongue lesions, and taste loss were the most commonly reported oral symptoms in patients with mild-to-moderate COVID-19. The most common general symptoms were tiredness and headache (63.9%), followed by dry cough, myalgia, sore throat, and fever. This study found 139 occurrences of oral symptoms, of which 52 were dry lips (27 tobacco non-users, and 25 tobacco users), and 11 were gingivitis (five non-users, and six tobacco users), and 12 tongue changes (eight non-users, and four tobacco users). Ageusia, or loss of taste sensation, was most commonly reported with or without other oral COVID-19 symptoms (55 occurrences: 36 non-users and 19 tobacco users). No significant differences were found in oral symptoms between tobacco non-users and tobacco users. There is a need to expand the routine examination protocol for patients during future respiratory pandemics, as monitoring oral health allows dentists to improve the management of oral sequelae during a pandemic.

COMPARISON BETWEEN NEBULISATION OF MGSO4 20 MG/KGBW WITH KETAMINE 0.5 MG/KGBW ON THE INCIDENT OF POST-OPERATIVE SORE THROAT DUE TO ENDOTRACHEAL INTUBATION IN PATIENTS UNDERGOING GENERAL ANESTHESIA IN DR. HASAN SADIKIN HOSPITALS BANDUNG

Post Operative Sore Throat (POST) is a Symptoms often experienced by patients after surgery under general anesthesia and endotracheal intubation. The incidence of POST is between 21-71.8. POST causes discomfort to patients which can prolong hospital stay. In this study, a comparison was made between MgSO4 nebulization 20 mg/ KgBW and ketamine nebulization 0.5 mg/ KgBW on the incidence of POST after general anesthesia at RSUP Dr. Hasan Sadikin Bandung . This study used a double blind randomized controlled trial design. 72 elective surgery patients were randomly divided into 2 groups. Group M was given MgSO4 nebulization while group K was given ketamine nebulization. Nebulization was performed 15 minutes before induction of general anesthesia. POST monitoring was performed at 1, 4 and 24 hours after extubation using POST scoring. In this study, it was found that the incidence of POST in group M, namely the 1st hour of 13.5, the 4th hour of 10.8 and the 24th hour of 0 was lower than that in group K, namely the 1st hour of 28.5, the 4th hour of 32.5 and the 24th hour of 0. Statistical test results p0.033 showed a significant difference in group M better than group K at the 4th hour in reducing the incidence of POST. MgSO4 and ketamine have antinociceptive and anti-inflammatory effects with the mechanism of action of blocking NMDA receptors that inhibit calcium influx that avoids central sensitization. MgSO4 also has a muscle relaxing effect and reduces airway mucus secretion, thus reducing the risk of trauma during endotracheal intubation. The conclusion of this study is that MgSO4 nebulization shows a lower incidence of POST than ketamine nebulization.

Effect of continuous measurement and adjustment of endotracheal tube cuff pressure on postoperative sore throat in patients undergoing gynecological laparoscopic surgery: a randomized controlled trial.

Postoperative sore throat (POST) is a common complication following endotracheal tube removal, and effective preventive strategies remain elusive. This trial aimed to determine whether actively regulating intraoperative cuff pressure below the tracheal capillary perfusion pressure threshold could effectively reduce POST incidence in patients undergoing gynecological laparoscopic procedures. This single-center, randomized controlled superiority trial allocated 60 patients scheduled for elective gynecological laparoscopic procedures into two groups: one designated for cuff pressure measurement and adjustment (CPMA) group, and a control group where only cuff pressure measurement was conducted without any subsequent adjustments. The primary outcome was POST incidence at rest within 24h post-extubation. Secondary outcomes included cough, hoarseness, postoperative nausea and vomiting (PONV) incidence, and post-extubation pain severity. The incidence of sore throat at rest within 24h after extubation in the CPMA group was lower than in the control group, meeting the criteria for statistically significant superiority based on a one-sided test (3.3% vs. 26.7%, P < 0.025). No statistically significant differences were observed in cough, hoarseness, or pain scores within 24h post-extubation between the two groups. However, the CPMA group had a higher incidence of PONV compared to the control group. Additionally, the control group reported higher sore throat severity scores within 24h post-extubation. Continuous monitoring and maintenance of tracheal tube cuff pressure at 18 mmHg were superior to merely monitoring without adjustment, effectively reducing the incidence of POST during quiet within 24h after tracheal tube removal in gynecological laparoscopic surgery patients. The study was registered at www.chictr.org.cn (ChiCTR2200064792) on 18/10/2022.

Sudan's rheumatic fever and rheumatic heart disease guidelines: a simplified approach in an endemic country

BackgroundRheumatic heart disease (RHD) is a preventable sequelae of group A beta hemolytic streptococcal infection leading to an immune reaction: acute rheumatic fever (ARF) and progressive heart valve dysfunction. RHD is the leading cause of acquired heart disease in children and young adults in Sudan and many low/middle-income countries. In 2018, the World Health Organization (WHO) issued a resolution for RHD mandating that each country adopt updated guidelines for ARF and RHD management. These current guidelines are mainly directed to primary healthcare workers.MethodsSudan’s Federal Ministry of Health (FMOH) in collaboration with the WHO East Mediterranean Regional Office (EMRO) assembled a committee for updating RHD guidelines. We conducted a systematic literature search from 2000 to 2022 in National Institute of Health Database (PubMed) under the following titles: streptococcal pharyngitis, acute rheumatic fever, rheumatic heart disease, benzathine penicillin. Best available, evidence-based practices for diagnosis and management of ARF/RHD were selected and adapted to Sudan's situation. The guidelines were critically appraised by the committee then endorsed to the FMOH and WHO EMRO Noncommunicable Disease Departments in January 2023. This paper describes the updated guidelines.ResultsSimplified algorithms are provided for diagnosis of bacterial pharyngitis including two clinical criteria: sore throat and the absence of viral symptoms in the target age group. A simplified algorithm for diagnosis and management of ARF is adopted using two levels of diagnosis: suspected case at primary level where penicillin prophylaxis is started and secondary/tertiary care where echocardiography is performed and diagnosis confirmed or excluded. Echocardiography screening is recognized as the standard method for early diagnosis of RHD; however, due to the anticipated limitations, its implementation was not adopted at this time. Streptococcal skin infection is included as a precursor of ARF and a detailed protocol for benzathine penicillin administration is described.ConclusionThe Sudan guidelines for ARF/RHD management were updated. Endorsement of these guidelines to FMOH and WHO EMRO is expected to improve control of RHD in the region.

Faecal shedding of SARS-CoV-2 from patients with asymptomatic and mild COVID-19 without gastrointestinal symptoms in Ghana

ObjectiveIn this study, we sought to determine whether faecal shedding occurs among SARS-COV-2 positive Ghanaians, as reported elsewhere. Hence we assayed for SARS-COV-2 in the stools of 48 SARS-COV-2 confirmed patients at the Ho Municipal Hospital in Ghana.ResultsOf the 48 COVID-19 patients, 45 (93.8%) had positive tests for SARS-CoV-2 faecal shedding. About 60% reported no respiratory symptoms, while only 2% (1 patient) reported gastrointestinal (GI) symptoms in the form of nausea. Other symptoms reported included headache (57.9%), weakness (57.9%), cough (52.6%), blocked/runny nose (47.4%), fever (31.6%), sore throat (31.6%), and shortness of breath (21.1%). One person complained of nausea (5.3%) Semi-quantitative comparison of the SARS COV-2 viral loads in matched respiratory and faecal samples using the cycle threshold (CT) values revealed no statistical differences. Furthermore, the duration between collection of respiratory and faecal samples did not have any direct influence on the differences in the CT values. This suggests that treatment and use of sewage for environmental surveillance of SARS COV-2 could be a potential public health countermeasure.

Supraglottitis: An airway emergency

Supraglottitis is a life-threatening condition and refers to inflammation of the epiglottis and the surrounding supraglottic structures. Children usually present with only a swollen epiglottis, termed epiglottitis. Fortunately, the incidence of epiglottitis in children has declined following routine Haemophilus influenzae type B vaccination, but the incidence in adults has increased. Supraglottitis has a high morbidity and mortality from the associated risk of airway obstruction. Therefore, early recognition and urgent secondary care referral is paramount. However, the presentation of this condition can be subtle and differs between children and adults; this can lead to difficulties in diagnosis. This article will review the clinical presentation and management of supraglottitis, an important differential for acute sore throat and hoarse voice.

Case Report: Branch retinal vein occlusion following COVID-19 vaccination and SARS-CoV-2 infection while taking oral contraceptives

Oral contraceptive use, vaccination for Coronavirus disease 2019 (COVID-19), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection are risk factors for venous thromboembolism. Branch retinal vein occlusion (BRVO) generally develops mid-60s patients. Herein, we present a case of BRVO caused by the above mentioned risk factors in a young woman. To the best of our knowledge, this is the first report about BRVO associated with oral contraceptives, COVID-19 vaccination, and SARS-CoV-2. A 21-year-old woman presented with loss of visual acuity in her right eye for 10 days. She had been receiving oral contraceptives for 2 years for oligomenorrhea before noticing ophthalmological symptoms. Despite having received two doses of an mRNA COVID-19 vaccine, she contracted COVID-19 and developed fever, sore throat, cough, low back pain, and general malaise about 40 days before the initial visit. However, only cough persisted for more than a month. The right eye showed BRVO with macular edema (ME). She did not smoke nor had diabetes or hypertension. Blood test results, including cardiolipin antibody IgG, were normal. She was treated with an intravitreal aflibercept injection. ME in the fundus showed rapid improvement and resolution. Although more than 20 months have passed since the first injection, there has been no relapse of ME. The combination of oral contraceptive use, COVID-19 vaccination, and subsequent SARS-CoV-2 infection could induce the development of venous thromboembolism, thereby leading to BRVO. Given that cases of COVID-19 have increased globally, patients with retinal vein occlusion who use oral contraceptives are likely to be encountered more frequently.

Case Report: Urothelial urethral carcinoma in HIV patient underwent total urethrectomy and perineal urethrostomy

Introduction HIV affects over 38 million people worldwide, affecting the immune system and leading to symptoms like fever, lymphadenopathy, and sore throat. High viral loads can lead to opportunistic infections and tumors. The life expectancy of HIV patients has increased due to high-efficiency combination anti-retroviral therapy. Urothelial carcinoma, a malignant development, damages the urinary canal lining. The connection between HIV and urinary cancers is unclear, the aims of this study to report a case of urethral urothelial Carcinoma in HIV patient who underwent total urethrectomy and perineal urethrostomy. Case presentation A 34-year-old male patient with a papilliferous lump on the glans penis for over six months was admitted to the hospital. Preoperative screening revealed HIV and a urethral mass was found. A partial urethrectomy was performed, revealing high grade papillary urothelial Carcinoma. Five months after surgery, the patient developed a recurrent lump, requiring a total urethrectomy, TUR (transurethral resection) of the mass in the prostatic urethra, and perineal urethrostomy. Conclusion Primary carcinoma of the urethra in HIV patient is an extremely rare case. To date, there is no consensus on the primary urethral carcinoma therapy. The treatment of primary urethral carcinoma is tailored specifically to the patient based on the location, histology, and stage of the carcinoma.

Integrating Epigenetics, Proteomics, and Metabolomics to Reveal the Involvement of Wnt/β-Catenin Signaling Pathway in Oridonin-Induced Reproductive Toxicity

Oridonin is the primary active component in the traditional Chinese medicine Rabdosia rubescens, displaying anti-inflammatory, anti-tumor, and antibacterial effects. It is widely employed in clinical therapy for acute and chronic pharyngitis, tonsillitis, as well as bronchitis. Nevertheless, the clinical application of oridonin is significantly restricted due to its reproductive toxicity, with the exact mechanism remaining unclear. The aim of this study was to investigate the mechanism of oridonin-induced damage to HTR-8/SVneo cells. Through the integration of epigenetics, proteomics, and metabolomics methodologies, the mechanisms of oridonin-induced reproductive toxicity were discovered and confirmed through fluorescence imaging, RT-qPCR, and Western blotting. Experimental findings indicated that oridonin altered m6A levels, gene and protein expression levels, along with metabolite levels within the cells. Additionally, oridonin triggered oxidative stress and mitochondrial damage, leading to a notable decrease in WNT6, β-catenin, CLDN1, CCND1, and ZO-1 protein levels. This implied that the inhibition of the Wnt/β-catenin signaling pathway and disruption of tight junction might be attributed to the cytotoxicity induced by oridonin and mitochondrial dysfunction, ultimately resulting in damage to HTR-8/SVneo cells.

Vaccine effectiveness against emerging COVID-19 variants using digital health data

BackgroundParticipatory surveillance of self-reported symptoms and vaccination status can be used to supplement traditional public health surveillance and provide insights into vaccine effectiveness and changes in the symptoms produced by an infectious disease. The University of Maryland COVID Trends and Impact Survey provides an example of participatory surveillance that leveraged Facebook’s active user base to provide self-reported symptom and vaccination data in near real-time.MethodsHere, we develop a methodology for identifying changes in vaccine effectiveness and COVID-19 symptomatology using the University of Maryland COVID Trends and Impact Survey data from three middle-income countries (Guatemala, Mexico, and South Africa). We implement conditional logistic regression to develop estimates of vaccine effectiveness conditioned on the prevalence of various definitions of self-reported COVID-like illness in lieu of confirmed diagnostic test results.ResultsWe highlight a reduction in vaccine effectiveness during Omicron-dominated waves of infections when compared to periods dominated by the Delta variant (median change across COVID-like illness definitions: −0.40, IQR[−0.45, −0.35]. Further, we identify a shift in COVID-19 symptomatology towards upper respiratory type symptoms (i.e., cough and sore throat) during Omicron periods of infections. Stratifying COVID-like illness by the National Institutes of Health’s (NIH) description of mild and severe COVID-19 symptoms reveals a similar level of vaccine protection across different levels of COVID-19 severity during the Omicron period.ConclusionsParticipatory surveillance data alongside methodologies described in this study are particularly useful for resource-constrained settings where diagnostic testing results may be delayed or limited.

Plain language summary: treatment of paroxysmal nocturnal hemoglobinuria with pegcetacoplan for 48 weeks (PEGASUS study)

What is this summary about? Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, serious blood disease, characterized by uncontrolled activation of the complement system that causes hemolysis (destruction of red blood cells). The complement component 5 (C5) inhibitor eculizumab was the first approved treatment for PNH. The PEGASUS trial compared eculizumab with pegcetacoplan, a new complement component 3 (C3) inhibitor. Because C3 is activated before C5, blocking C3 would also block C5; thus, a C3 inhibitor might prevent hemolysis more completely than a C5 inhibitor in patients with PNH. During the first 16 weeks of PEGASUS, patients received either pegcetacoplan or eculizumab; results were published separately. This summary describes results of the following 32 weeks of PEGASUS, during which all patients received pegcetacoplan to evaluate if pegcetacoplan continued to be effective and safe for up to 48 weeks. What were the results? Pegcetacoplan continued to be effective in participants who received it throughout the study and improved symptoms in participants who switched from eculizumab. The most common adverse events (side effects) were skin irritation at the injection site, hemolysis, nasopharyngitis (runny nose and sore throat), and diarrhea. Adverse events were serious and related to pegcetacoplan in 4 of 77 (5%) patients; all patients recovered from these events. What do the results mean? Pegcetacoplan improved symptoms and was well tolerated for up to 48 weeks by most patients in PEGASUS, suggesting that adult patients with PNH may benefit from long-term pegcetacoplan treatment.

Adult-onset Still’s disease: analysis of a monocentric cohort of patients

Objective Adult-onset Still’s disease (AOSD) is a multigenic autoinflammatory disease with a severe systemic involvement. Because of the rarity of the disease, most published cohorts are multicentric. The aim of this report is to describe a monocentric cohort of AOSD patients, reporting clinical features and response to therapy in a long follow-up. Method Thirty-eight patients, attending the Clinical Immunology Unit and fulfilling Yamaguchi, Fautrel, or Daghor-Abbaci classification criteria for AOSD, were recruited for this study. In all patients, clinical and serological data were collected at diagnosis and every 6 months thereafter. The Pouchot score was calculated at every visit. Results Fever, arthromyalgia, and skin rash were the most frequent manifestations, followed by lymphadenopathy, sore throat, arthritis, splenomegaly, hepatic involvement, pleuropericarditis, and weight loss. As far as the disease course is concerned, 25% presented a monocyclic and 35% a polycyclic pattern, and 40% developed chronic articular involvement. Severe complications were observed at disease onset in 21% of the patients. All of the patients were treated with steroids; 74% also received conventional synthetic disease-modifying anti-rheumatic drugs (methotrexate in most cases) and 71% biological disease-modifying anti-rheumatic drugs (interleukin-1 inhibitors in most cases). Therapeutic switching for lack/loss of efficacy or adverse drug reactions was necessary in 66%. Conclusion The analysis of this cohort confirms that AOSD is a complex, severe, and heterogeneous disease. However, despite long-term treatment and comorbidities, therapies are effective and well tolerated. The therapeutic armamentarium now available allows long-lasting remission with low immunosuppression to be achieved in most patients.

Examination of Ulcero-Proliferative Lesions of Oropharynx and Oral Cavity- A Clinical Perspective

 Introduction Patients often present with ulcero-proliferative lesions of the oropharynx and oral cavity in the outpatient department (OPD). These lesions have a negative impact on the patients' health, so it's critical to make an accurate diagnosis and administer the right care.  Aim of the Study: To determine the proportion of patients who exhibit different ulcero-proliferative lesions clinical characteristics in the oropharynx and oral cavity.  Patients and Methodology: This is prospective study done at Department of ENT, Guntur Medical College, spanning a period of 18 months. This study included patients with ulcero- membranous lesions in the oropharynx and oral cavity, regardless of age. This study excluded Patients who had radiation therapy soon before developing the illness and who had traumatic injuries but no infection. Detailed history including personal, family and medical history were noted. Local and general examination was done. Selected patients were subjected to investigations like routine blood investigations, gram stain, albert’s stain, KOH mount, culture and sensitivity, peripheral smear, serology, FNAC, HPE, USG, chest x ray, CT neck, MRI.  Results In the current study, men dominated women (65.69%) and the most prevalent age group participating was 41–60 years old (45.09%). The most typical symptoms of the throat were odynophagia, burning sensation, dysphagia, and throat pain. 5.9% of the patients had nose issues and 14.7% had associated ear complaints. General symptoms included fever in 10.7% of cases, weight loss in 23.5%, general weakness in 15.6% of cases, and skin lesions in 6.9% of cases. Systemic disorders such as HIV was present in 3.9%, hypertension in 25.4%, and diabetes in 34.3% of cases. Risk factors include chewing tobacco (17.6%), drinking alcohol (14.7%), smoking (43.1%), and having previously been exposed to radiation (0.9%). The tongue was the most frequently afflicted site in this study (44.1%), followed by the palate (29.4%), the buccal mucosa (15.6%), the tonsils (8.8%), the lips (7.8%), the alveolus (2.9%), and the RMT (1.9%). Neoplastic etiology accounted for 41.1% of the total etiology discovered. It was followed by inflammatory (31.3%), infectious (20.5%), and miscellaneous (6.8%) etiologies. 52.9% of patients had conservative care, 36.2% had oncosurgery team treatment through surgery, and 10.7% had radiation therapy. Of the patients with neoplastic etiology, 10.7% had radiation therapy.  Conclusion: The incidence of cancers rises in the adult population with increased habits like smoking and chewing nicotine in any form. A high degree of suspicion is required when treating oral ulcers, particularly those that are chronic. The gold standard for confirming the diagnosis is always a biopsy and a histopathological examination.

Leveraging artificial intelligence to identify high-risk patients for postoperative sore throat: An observational study.

Postoperative sore throat (POST) is a prevalent complication after general anesthesia and targeting high-risk patients helps in its prevention. This study developed and validated a machine learning model to predict POST. A total number of 834 patients who underwent general anesthesia with endotracheal intubation were included in this study. Data from a cohort of 685 patients was used for model development and validation, while a cohort of 149 patients served for external validation. The prediction performance of random forest (RF), neural network (NN), and extreme gradient boosting (XGBoost) models was compared using comprehensive performance metrics. The Local Interpretable Model-Agnostic Explanations (LIME) methods elucidated the best-performing model. POST incidences across training, validation, and testing cohorts were 41.7%, 38.4%, and 36.2%, respectively. Five predictors were age, sex, endotracheal tube cuff pressure, endotracheal tube insertion depth, and the time interval between extubation and the first drinking of water after extubation. After incorporating these variables, the NN model demonstrated superior generalization capabilities in predicting POST when compared to the XGBoost and RF models in external validation, achieving an area under the receiver operating characteristic curve (AUROC) of 0.81 (95% CI 0.74-0.89) and a precision-recall curve (AUPRC) of 0.77 (95% CI 0.66-0.86). The model also showed good calibration and clinical usage values. The NN model outperforms the XGBoost and RF models in predicting POST, with potential applications in the healthcare industry for reducing the incidence of this common postoperative complication.

Jiegeng decoction ameliorated acute pharyngitis through suppressing NF-κB and MAPK signaling pathways

Ethnopharmacological relevanceJiegeng decoction (JGD), consisting of Glycyrrhizae Radix et Rhizoma and Platycodonis Radix at the ratio of 2:1, is a classical Chinese medicine prescription firstly recorded in "Treatise on Febrile Diseases". JGD has been extensively utilized to treat sore throat and lung diseases for thousands of years in China. However, the pharmacological effect and mechanism of JGD on acute pharyngitis (AP) remain unclear. Aim of the studyOur research aimed to reveal the pharmacological effect of JGD on AP and its potential mechanisms. Materials and methodsThe chemical components of JGD were analyzed based on the UPLC-MS analysis. The anti-inflammatory effect of JGD was evaluated by NO production using the Griess assay in RAW.246.7 cells. The mRNA expression of iNOS, IL-1β, IL-10, TNF-α, IL-6 and MCP-1 was determined by qRT-PCR in vitro. A 15% ammonia-induced AP model was established. The histopathology, the inflammatory cytokines IL-6 and MCP-1 in serum and the apoptosis-related genes caspease-8 and caspease-3 were determined by H&E staining, ELISA and qRT-PCR, respectively. The expression levels of p-p65, p65, p-JNK, JNK, p-p38, p38, p-ERK1/2, ERK1/2, and COX2 were measured through western blotting. ResultsNine compounds, including liquiritin, liquiritin apiosde, liquiritigenin, platycodin D, platycoside A, licorice saponin J2, licorice saponin G2, glycyrrhizic acid, and licochalcone A, were identified. JGD significantly inhibited NO production and regulated the mRNA expression levels of cytokines in LPS-stimulated RAW264.7 cells. The results of in vivo experiments confirmed that JGD ameliorated AP through improving the pathological state of pharyngeal tissue, decreasing the serum levels of IL-6 and MCP-1 and preventing the tissue mRNA expression of caspease-8 and caspease-3. Furthermore, JGD also inhibited the NF-κB and MAPK pathways in the AP model. ConclusionsThis study suggested that JGD could alleviate AP through its anti-inflammation via NF-κB and MAPK pathways, which supported the traditional application of JGD for the treatment of throat diseases.

Role of preoperative zinc, magnesium and budesonide gargles in Postoperative Sore Throat (POST) - a randomised control trial.

Post-operative sore throat (POST) has an incidence ranging from 21 to 80%. To prevent the development of POST, several pharmacological measures have been tried. Aim of this study was to compare the efficacy of preoperative zinc, magnesium and budesonide gargles in reducing the incidence and severity of POST in patients who underwent endotracheal intubation for elective surgeries. We conducted a prospective, randomized, double-blind, controlled equivalence trial in 180 patients admitted for elective surgical procedures under general anaesthesia. Patients were randomised into three groups; group Z received 40mg Zinc, group M received 250mg Magnesium Sulphate and group B received 200µg Budesonide in the form of 30ml tasteless and colourless gargle solutions. Sore throat assessment and haemodynamic recording was done postoperatively at immediate recovery (0h) and 2, 4, 6, 8, 12 and 24h post-operatively. POST was graded on a four-point scale (0-3). POST score was comparable at all recorded time points i.e. 0,2,4,6,8,12 and 24h. Maximum incidence was seen at 8h in group B (33.3%) and the minimum incidence was at 24h in group Z (10%) (p > 0.05). It was found that the incidence of POST was more in the surgeries lasting longer than 2h in all groups. This difference was found to be statistically significant in Groups M and B. The incidence of POST was found to be comparable between laparoscopic and open procedures. Magnesium, zinc and budesonide have an equivocal effect in the prevention of POST at different time points. The incidence of sore throat increases significantly in surgeries lasting more than two hours if magnesium or budesonide have been used as premedicant. Duration of surgery is an independent predictor for POST. CTRI/2021/05/033741 Date-24/05/2021(Clinical Trial Registry of India).

Self-Perceived Vocal Symptoms and Discomfort in Amateur Church Singers

PurposeTo analyze self-perceived vocal symptoms and discomfort in amateur church singers and compare them between genders and church types. MethodsIt was a quantitative cross-sectional study involving 99 amateur church singers aged between 18 and 59 years. Data collection was carried out through the completion of a socio-demographic questionnaire, the Voice Symptom Scale (VoiSS), and the Vocal Tract Discomfort Scale (VTDS). The Mann-Whitney test was used for comparisons, and Spearman's correlation test was used for analyzing correlations between scale scores. The adopted significance level was 5% (p <0.05). ResultsThere was a prevalence of females (71.7%), amateur singers from Protestant churches (73.7%), with a mean age of 27.5 years. The average VoiSS total score was 22.6 points, the "limitation" domain was 12.3, the "emotional" domain was 2.55, and the "physical" domain was 7.7. The most self-perceived sensations in the VTDS were "dryness," "sore throat," and "itchiness" with mild to moderate intensity. There was a statistically significant difference between genders (p<0.05) and a positive correlation from weak (r=0.212) to strong magnitude (r=0.660) between vocal symptoms and vocal tract discomfort. There was no statistically significant difference between types of churches. ConclusionAmateur singers self-report high levels of vocal symptoms, which impact limitation, emotional, and physical domains. Furthermore, they experience vocal tract discomfort sensations, with dryness being the most frequently reported, followed by sore throat and itching. No significant differences were found between the scale scores and church types. However, females reported a greater frequency and intensity of vocal tract discomfort sensations. The greater the self-reported vocal symptoms in this population, the higher their self-reported frequency and intensity of vocal tract discomfort sensations. These findings underscore the importance of addressing vocal health issues in amateur singers to enhance their overall well-being.
